   Car stops accelerating and shifts into neutral without warning I nearly got hit from behind. I have consulted several other Mercedes vehicle owners and all had the same issue. Two of the other owners stated that this happened on the interstate and was very lucky they were not involved in a collision. Both vehicles were GLC 300. Mercedes does not seem to have an answer to the issue and all previous owners traded vehicles for fear of dying.

   On Tuesday, June 24th, 2025, the glass panel located between the windshield and sunroof on my 2020 Mercedes-Benz C43 AMG unexpectedly detached and flew off while driving.

   This has happened a couple of times to me so far. I have been driving down the road (today it was the highway) and my car fell out of gear into neutral and would not go back into gear unless I restarted the car. Every time it has happened, I have had to coast it to a safe spot to restart the car to get it back into gear. Not having power and needing to coast it to safety is a risk to others because I have no control to get myself to safety in some situations. No dealer has…
